Mechanism of Directional Energy Transfer and Synergistic Control of Dynamic Burden-Blasting Effects in Underwater Hole-by-Hole Blasting in Complex Aquatic Environments

Geofluids
This study addresses the challenge of simultaneously controlling rock fragmentation and vibration during underwater rock blasting in complex environments. The Wuzhou Siliang River underwater blasting project was adopted as a case study.

Adaptation of Echinococcus Multilocularis to Oxidative Stress Depends on EmPDK‐Mediated Metabolic Reprogramming

Advanced Science, EarlyView.
Metabolic adaption presents a vital survival strategy for E. multilocularis. This study identifies EmPDK as a central metabolic regulator governing glucose metabolic reprogramming. Oxidative stress activates EmHIF1α to induce EmPDK expression. Mechanistic characterization reveals this ROS/EmHIF1α/EmPDK axis drives glycolytic reprogramming to sustain ...

Numerical simulation of deformation and hole position shift in extrusion process of four-hole propellant

Scientific Reports
Four-hole propellant were prepared by solvent extrusion. The polyflow module of ANSYS software was used to simulate the hole position deviation and shape change in the extrusion process of four-hole propellants.

Experimental and numerical study on protective effect of RC blast wall against air shock wave

Defence Technology
Prototype experiments were carried out on the explosion-proof performance of the RC blast wall. The mass of TNT detonated in the experiments is 5 kg and 20 kg respectively. The shock wave overpressure was tested in different regions.

Blasting in densely jointed rock to obtain slabs

, 1995
The economic return of rock blasting is not provided by brute volume of broken rock, rather by the amount of marketable product. That i s the case of the porphyry quarries of Trento district, whose output is mainly absorbed by road paving and building ...

A Personalized Haplotype‐Resolved Near‐Gapless Genome Framework for Somatic Variant Discovery in Hepatocellular Carcinoma

Advanced Science, EarlyView.
A patient‐specific, haplotype‐resolved genome framework improves detection and interpretation of somatic variants in hepatocellular carcinoma. Using multi‐platform sequencing, the personalized assembly resolves complex regions including centromeres and MHC/HLA loci, enhances structural variant discovery, and links regulatory alterations to allele ...

Unveiling the Taxonomic Diversity and Unprecedented Biosynthetic Treasure of the Phylum Myxococcota

Advanced Science, EarlyView.
Natural products remain vital sources of therapeutics, and the phylum Myxococcota constitutes an especially rich reservoir for them. Based on decades of microbiological efforts, we present 154 new Myxococcota genomes and revise taxonomy quadrupling the number of families and genera.
